1. What is WCAG, and why is it important for UX designers?
WCAG (Web Content Accessibility Guidelines) is an internationally recognized set of guidelines that ensure web content is accessible to people with disabilities. UX designers should follow WCAG to create inclusive experiences that accommodate users with visual, auditory, cognitive, and motor impairments.
2. What is the difference between WCAG levels A, AA, and AAA?
Level A
Basic accessibility requirements that all websites should meet
Fundamental access requirements
Minimum level of compliance
Level AA
Recommended standard for most organizations
Covers broader range of disabilities
Balance of achievable and impactful requirements
Level AAA
Highest level of accessibility
Ideal for highly inclusive experiences
Most comprehensive but challenging to achieve
3. Are there other accessibility standards besides WCAG that UX designers should know about?
Yes, in addition to WCAG, UX designers should be aware of:
Section 508 (U.S. government accessibility standard)
EN 301 549 (European standard for digital accessibility)
ADA (Americans with Disabilities Act) (U.S. law requiring digital accessibility)
COGA (Cognitive and Learning Disabilities Accessibility Task Force) (focused on cognitive accessibility)
4. How does accessibility apply beyond WCAG conformance?
WCAG focuses on technical guidelines, but true accessibility involves usability for diverse audiences. This includes:
Designing for cognitive disabilities (e.g., dyslexia, ADHD)
5. Should we follow APCA instead of WCAG contrast guidelines?
APCA offers a more dynamic and perceptually accurate approach to color contrast, but WCAG is still the official compliance standard. Designers can reference APCA for improved readability while ensuring their designs meet WCAG contrast requirements.
Component Design & Implementation
6. What are the most common accessibility mistakes in UX design?
Using low-contrast text that is hard to read.
Relying only on color to convey meaning.
Not providing alternative text for images.
Poor keyboard navigation and missing focus indicators.
Using non-standard components that don’t work with assistive technologies.
Overcomplicated interactions that increase cognitive load.
7. How can we make interactive components more accessible?
Ensure buttons and links have clear, descriptive labels.
Provide sufficient contrast for text and interactive elements.
Implement keyboard navigation and focus management.
Use ARIA (Accessible Rich Internet Applications) attributes where necessary, but not as a substitute for semantic HTML.
Test with real users, including those who rely on screen readers and keyboard navigation.
8. How do I ensure that my design system components remain accessible?
Build accessibility checks into your design review process.
Use automated testing tools alongside manual testing.
Maintain clear documentation on accessibility requirements for each component.
Encourage cross-functional collaboration between UX, developers, and accessibility experts.
9. What’s the best approach for handling accessibility in UI animations?
Allow users to disable animations if they have motion sensitivity.
Avoid flashing or rapid movement to prevent seizures (WCAG 2.3.1).
Ensure animations do not block essential content or interactions.
10. What should be considered when designing forms for accessibility?
Label all form fields clearly and associate labels properly using
Use placeholder text only as a supplement, not a replacement for labels.
Provide error messages with clear instructions on how to fix input mistakes.
Ensure form elements are keyboard accessible and have a visible focus state.
11. What are common accessibility pitfalls in mobile UX design?
Small touch targets that make it difficult for users with motor disabilities to tap.
Poor color contrast in dark mode designs.
Overuse of gestures without alternatives like buttons.
Lack of screen reader-friendly content hierarchy.
12. How can I balance accessibility with brand aesthetics?
Use high-contrast colors while maintaining brand consistency.
Offer users personalization options (e.g., font size, dark/light mode).
Prioritize clarity and usability over decorative elements.
Testing & Tools
13. How do we test for cognitive accessibility beyond WCAG guidelines?
Use plain language and avoid unnecessary jargon.
Reduce cognitive load by using progressive disclosure.
Offer multiple ways to complete tasks (e.g., text, voice, touch).
Test designs with users who have cognitive disabilities.
14. What tools can UX designers use to check for accessibility issues?
Reduce cognitive overload by summarizing responses and providing clear action steps.
Offer adaptive interactions, such as confirming complex tasks before proceeding (e.g., “Would you like me to repeat that in a simpler way?”).
24. How do I write AI prompts that prioritize accessibility?
If requesting AI-generated UI suggestions, include “keyboard navigable” and “voice-command compatible” in the prompt.
For AI-generated content summaries, request “concise, structured, and screen-reader friendly formats.”
When designing AI for voice interfaces, specify “clear, slow speech output with optional speed adjustments.”
25. What are best practices for AI-generated captions and transcripts?
Ensure captions are synchronized with speech and include non-verbal cues (e.g., “[laughter]” or “[music playing]”).
Use human-edited captions for accuracy in professional content.
For transcripts, structure them clearly, including speaker labels and timestamping.
26. How can AI assist in creating accessible UX content?
Use AI to generate accessible alt text based on image context.
Generate multiple readability levels for content, ensuring accessibility for users with different literacy levels.
Suggest inclusive language alternatives to avoid ableist terms (e.g., recommending ‘person with low vision’ instead of ‘visually impaired’ to emphasize person-first language where appropriate).
Quick Reference Section
Common Myths About Accessibility
Myth 1: “Accessibility is only for blind users”
→ False! It benefits users with diverse disabilities, including mobility, cognitive, and auditory impairments
Myth 2: “ARIA fixes everything”
→ False! ARIA should be used only when semantic HTML doesn’t provide the necessary accessibility
Myth 3: “Accessibility is too expensive”
→ False! Implementing accessibility from the start saves money by reducing costly retrofitting later

Accessible Component Design Decision Tree
How to Use This Decision Tree:
This decision tree helps you check if your component meets accessibility standards. Follow these steps in order:
Start with WCAG A
Make sure everyone can use your component
Check keyboard access, labels, focus visibility, and alt text for images
Move to WCAG AA if A is complete
Improve contrast so text is easy to read
Make sure users can resize text without breaking the layout
Add captions for videos and check focus order
Check if AAA is needed
Some projects, like government or inclusive products, may need extra features
AAA includes sign language for videos, high contrast text, and more customization options
Your component is ready when all required levels are met.
